Comment (by nickm):

 These functions seem to be a maze of linear operations over the entire set
 of nodes: yuck.  We need to look for better ways. One choice is to memoize
 results at some level; another is to precompute results at some level;
 another is to replace linear low-level ops with sublinear ones.
